Um I have a situation

putting "kill her" as an option just tells me how immaturely you're looking at the situation and how you're not thinking why she did this. you're thinking in the retrospect "why did my friend have to backstab me like that just because i tell her this doesn't mean she has to blab about it"

lemme put this in a point of view you can understand. it may not be a good view, but i feel the need to drill it in your head
you're the one who told her about this crush. you disclosed this information to her, and if you didn't want her to say anything, why didn't you tell that to her?"
now, i'm not saying you didn't. i don't know if you did. i'm also not saying that this is your fault. it is something to keep in mind though.

telling her crush she likes him will NOT SOLVE ANYTHING, AND WILL PROBABLY COST YOU A FRIEND. REVENGE, OR PAYBACK OF ANY SORT WILL NOT HELP YOU. IT IS A CHILDISH RESORT. just, no.

ignoring the problem will not make it go away. it will still be there, and it will lurk in your mind for as long as possible. ignorance may be bliss, but there are some situations where it doesn't apply. she may take your ignorance in a negative connotation.

being friends is optional with the boy (if that's what you're referring to), but only if you feel comfortable with it.

i suggest you tell your friend that you didn't want her to tell everyone about it, and that personal information like this is meant to be kept between friends, not become some petty gossip story. as for the boy, you could probably confirm the feelings you have for him, but in reality what you do is up to you.

you could easily ignore everything i said, that's fine. in reality, you control what happens next. i'm just giving you different views so that you can choose your path carefully

ignore the problem and pretend it's not awkward. it only makes it worse if you make a big deal out of it.

Well maybe your friend didn't mean to make you feel embarrassed by her telling your crush that you like him, she might have wanted to let him know so you wouldn't have to tell him. I think you should ignore the problem or try to tell her that you didn't like what she did....but I'm guessing that you two aren't very good friends anyway if you want to kill her so badly....

Why is this such a big deal?

I mean, he now knows you like him right?

I'd just forget the problem, because it doesn't really seem like one.

You choose what you think is right/needs to be done. Just know you'll go to jail if you kill her. ^-^

You can choose whichever you think is right. I personally would just ignore the problem and not make a big deal out of it and I would not kill her. She's your friend,sure she told him you liked him in front of everybody but you can simply ignore her for a bit until she realizes she shouldn't have done that. Deciding to kill her is taking things way too far and will just make more problems.

Why do you care so much about the problem if it's already been said in front of people?
Having fear of something you think is not okay isn't a bad thing, if you want to set things right then do it.

All of the above.

Well did this boy accept you?
